What is the purpose of using EDTA in vacuum blood collection tubes?
EDTA acts as an anticoagulant by binding calcium ions in the blood, preventing clotting. This ensures that the blood sample remains stable and suitable for hematological tests such as CBC, hemoglobin estimation, and platelet counting, providing reliable and accurate diagnostic results.
What is the difference between EDTA K2 and EDTA K3?
EDTA K2 is a powdered form that better preserves red and white blood cell structure, while EDTA K3 is a liquid form often used in automated analyzers. Both provide excellent anticoagulant performance, but K2 is generally preferred for higher morphological accuracy in hematology testing.
What certifications do the Siny EDTA tubes have?
The Siny tubes are CE, ISO, and FDA certified, ensuring compliance with international quality and safety standards. These certifications guarantee superior product reliability, sterility, and precision suitable for global medical and laboratory applications.
